DISSOLVED OXYGEN
Industrial Grade Portable with
Extended Range
HI 98186 dissolved oxygen meter includes barometric
pressure measurement and calibration with a user
selectable unit (mmHg, inHg, atm, mbar, psi, kPa) along
with salinity, pressure and temperature compensation.
• Extended range up to 50 ppm
BOD Parameters and Records
All necessary parameters for BOD testing can be
set and displayed at once.
A list of all saved BOD data can be easily
retrieved and shown on the LCD display.

• Built-in barometer
• Salinity, pressure and
temperature compensation
Inductive charger
BOD Results
BOD is calculated in mg per liter from the
difference between the initial and final
dissolved oxygen concentration readings.
Batteries can be recharged
using
HANNA’s
inductive
recharger. Simply leave the meter on the charger for a
few hours and you’re ready to go. The charger can be
powered using the included HANNA adapter.

Dissolved Oxygen
Calibration
SOUR Results
Measured in mg of oxygen consumed per g of
volatile suspended solids per hour.
BOD gives an indication of the biodegradable
organic material present in a sample of water.
The dissolved oxygen concentration is
measured before and after an incubation
period of 5 days and the BOD is calculated in
mg per liter from the difference.
OUR and SOUR are used to determine the
oxygen consumption or respiration rate. OUR
is measured in mg of oxygen consumed per
liter per hour, and SOUR is measured in mg of
oxygen consumed per gram of volatile
suspended solids per hour.
